You are going to have to crack the case on your computer.

First, disconnect all hardware attached except for your mouse, keyboard and
monitor.

Second, disconnect any additional hard drives. You want only the hard drive
connected that you plan to install Vista upon.

Third, uninstall any antivirus, anti spyware programs you may have
installed. Uninstall any program known to cause compatibility problems with
Vista including, but not limited to anything from Roxio or Nero. You have to
do research to find out what you have that may be the culprit.

The best way - in my estimation - is to boot from the retail DVD and do a
clean install - with only the above hardware connected.
